Video: Kevin McDermott on the performance from one star vs five star animals

Kevin McDermott Sheep IReland explains some of the difference found in the CPT between 2013 and 2015 when comparing 1 Star vs 5 Star at an individual trait level over 7,500 animals. In this case the 5 Star, 5 Star mating combination, resulted in an extra 17% lamb at the point of weaning compared to the 1 Star, 1 Star mating combination. The differences are stark and prove that extra profit can be made if continually selecting 4 or 5 star animals for breeding. Granted the difference here are using the extremes, if even a fraction of this increase could be applied across the national flock it would have a major impact on the industry.
